Actually the Rectifer is the thing that change AC current to DC current. Diodes keeps current going in one way. a fuse controls high/unwanted amps, it does not control directional current flow. Have you ever seen or hook up a batter backwards? Some cars it might not do anything but some will striaght fry the computers or wont allow the car to start. Well with no Diodes/no alternator this is what can happen.Black70Fastback said:oy, its not like the car shuts the battery off once its running. basically the alt. is hooked up to the posative side of the battery and the car is ran off that. while the alt. is operating, the car should be at 14.4 volts and when its not, it should be at 12 volts. this might hinder injector performance/ignition but minimally and he has to atleast try it
the diodes you speak of are there for the basic principle of an alternator. a diode is one way electric vavle so to speak. the alt. makes an AC or "alternating" current. wierd huh? the diode cuts that down to a DC (direct current) that a car is designed to use.
as far as spikes go, thats what fuses are for. so as long as hes not using the "lincoln fuse" in anything he should be fine. a piece of wire or etc.
lincoln fuse is a term from the old style screw in houshold fuses. when a fuse blew, people would screw it out, put a penny (lincoln) under it and screw it back in. meaning it was hotwired and stuff could be fried or houses could be burned down.

I think your talking about the voltage regulator diodes. They're the prime reason you should never jump a vehicle while the other one is still on. The load from two engines will pull too much current across those diodes you're talking about and doesn't do well on there life. OK really off subject there Point is your rightxYoung347x said:Well the battery starts the car then the alternator allows it to run and charges the battery. The battery will stop working once the engine start rolling. In the alternator there's this one thing that prevents spikes. I think its called Diodes, it only allows current to flow one way. If you're just running the car with the battery it might make a spike and can fry your computer. The battery don't have diodes so it can produce spike any time it wants. Get what Im saying?
BTW, those track guys that is doing it is because they probably are non efi and/or have control of their computer with a different programmer.
